Hydroxypropyl Methylcellulose
HydroxypropylMethylcellulose (HPMC) a i ʻole hypromellosehe mea hoopukas o Methyl cellulose nā etera. ʻo iahe fibrous keʻokeʻo keʻokeʻo a ʻeleʻele pahacellulose eterapauda. ʻO ia ka cellulose i kēia manawa nā etera me ka hana maikaʻi loa ma ka honua, hoʻohui i ka mānoanoa, hoʻokuʻu, hoʻopuehu, emulsifying a hoʻopaʻa. Hydroxypropyl methyl cellulose (HPMC) ʻAʻole ʻona, maʻalahi e hoʻohana, a hiki ke hoʻoheheʻe ʻia i ka wai. He polyanion ia i loko o ka hoʻonā wai a loaʻa nā waiwai kino kū hoʻokahi. ʻO ka hana kūikawā e like me ka lalo:
